菌根在更可持续棕榈油种植中的作用

来源: 本站  类别:行业动态  更新时间:2010-01-05  阅读
      在许多发展中国家,棕榈油是一种重要并且具有发展前景的作物。然而,棕榈油的引入,给自然资源带来了压力,因为它需要一块完整的土地,而这些土地先前可能是用来种植其他作物或者是被森林覆盖的。这就导致了需要引起注意的环境问题。因此,新的种植园需要努力寻求一种可持续发展方式,以减少棕榈油种植给生态系统造成的影响,同时又能给农民带来最大的产量和最高的生产率。丛枝菌根真菌(AMF)技术的应用,是既保证农艺植物的健康,同时不损害生态系统利益的一种选择。AMF有可能提高传统农业的生产力,同时对农业生态系统的可持续运作起到关键性作用。这篇文章通过对棕榈油种植园更可持续的管理方式和对AMF的合理应用,来深刻解构AMF技术的应用在棕榈油种植中产生的效益。

Oil palm is a significant and developing crop in many developing countries. The introduction of oil palm puts pressure on natural resources because it is often planted in cleared-cut land that previously supported other crops or was forested. This has led to environmental concerns which require attention. Hence it is important that new plantations are managed in a sustainable way to reduce the impact of oil palm cultivation on ecosystems whilst maximising yield and productivity to farmers. The application of arbuscular mycorrhizal fungi (AMF) technology is one option that can benefit both agronomic plant health and ecosystems. AMF have the potential to increase conventional agricultural productivity and are crucial for the sustainable functioning of agricultural ecosystems. This paper provides an insight into how AMF application might benefit oil palm cultivation through more sustainable management and the practical use of AMF for oil palm plantations.
